Spring 事务管理 @Transactional 行为
Spring Transaction Management @Transactional behavior
我想知道 Spring @Transactional 如何适用于以下编码方案。对于此示例,我使用 Spring 4 + Hiberante 5 和 Oracle 19C 数据库。
示例 1:
@Service
public class UserService {
@Transactional(readOnly = true)
public void invoice() {
createPdf();
// send invoice as email, etc.
}
@Transactional(propagation = Propagation.REQUIRES_NEW)
public void createPdf() {
// ...
}
}
示例 2:
@Service
public class UserService {
@Autowired
private InvoiceService invoiceService;
@Transactional(readOnly = true)
public void invoice() {
invoiceService.createPdf();
// send invoice as email, etc.
}
}
@Service
public class InvoiceService {
@Transactional(propagation = Propagation.REQUIRES_NEW)
public void createPdf() {
// ...
}
}
谢谢
示例 1:当您从 inside
您的服务调用 createPDF 方法时,@Transactional(REQUIRES_NEW) 注释将有效地 ignored
。不会有新交易开启。
示例 2:当您调用另一项服务时,该服务包装在事务代理中,您将得到一个 new transaction
,因为注解得到尊重。
